Design and Implementation of an Intelligent Multimeter based on Android Technology
Upgraded and transformed the existing multimeter to meet the needs of train debugging in a certain host fac-tory,so as to enable it to have IoT functionality.Firstly,hardware scheme design was carried out,and the internal circuit of the multimeter was modified.Then a detailed software design was carried out,and we added networking,login,display,and data storage functions on top of the original measurement functions of traditional multimeter.It could communicate with the higher-level MES platform through the MQTT protocol,and receive and send various information and commands in a task driven manner.Through actual testing,it could be seen that the intelligent multimeter met the expected require-ments of this design when running online.
